4-[2-[tert-butyl(dimethyl)silyl]oxyethyl]aniline

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The compound (1.65 g, 5.86 mmol) prepared in step 1 was dissolved in ethyl acetate (20 ml), added with 10%-palladium (Pd) (165 mg) at room temperature. The reaction mixture was stirred for 3 days under hydrogen gas. 10%-palladium (Pd) was removed by using celite-filter and the filtrate was concentrated under reduced pressure. The residue was then purified by flash column chromatography (ethylacetate:hexane=1:4) to obtain the title compound (1.4 g, yield: 95%, colorless oil). 10%-palladium (Pd) was removed by using celite-filter the filtrate was concentrated under reduced pressure The residue was then purified by flash column chromatography (ethylacetate:hexane=1:4)
